  • Publication number: 20200369580
    Abstract: Processes are described for isomerizing one or more C14-C24 alpha olefins to produce an isomerization mixture comprising one or more C14-C24 internal olefins comprising contacting an olefinic feed comprising the one or more C14-C24 alpha olefins with a catalyst under isomerization conditions, wherein the catalyst comprises a microporous crystalline aluminosilicate having an MWW framework. The resulting isomerization mixture typically exhibits a low pour point with maintained biodegradability properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.

  • Publication number: 20200325085
    Abstract: Ebullated bed reactors may be used to synthesize olefin compositions exhibiting low sediment toxicity and favorable pour points. The olefin compositions are formed by isomerizing linear alpha olefins (LAOs) into linear internal olefins (LIOs), skeletal isomerized branched olefins, or any combination thereof. Methods for preparing olefin compositions comprising LIOs and, optionally, branched olefins may comprise: providing an olefinic feed comprising one or more LAOs, and interacting the olefinic feed with a plurality of catalyst particulates in an ebullated bed reactor to form an isomerized product. The catalyst particulates are effective to isomerize the one or more LAOs into one or more of LIOs, skeletal isomerized branched olefins, or combinations thereof. The isomerized product may be incorporated in drilling fluids, particularly those intended for subsea use, due to their favorable environmental profile and low pour points.

  • Publication number: 20190105626
    Abstract: Systems and methods are provided for conversion of light paraffinic gases to form liquid products in a process performed in a fixed bed radial-flow reactor. The light paraffins can correspond to C3+ paraffins. Examples of liquid products that can be formed include C6-C12 aromatics, such as benzene, toluene, and xylene. The fixed bed radial-flow reactor can allow for improved control over the reaction conditions for paraffin conversion in spite of the fixed bed nature of the reactor. This can allow the process to operate with improved efficiency while reducing or minimizing the complexity of operation relative to non-fixed bed reactor systems.

  • Patent number: 10196571
    Abstract: Methods are provided for converting lignin-containing biomass into compounds that are more readily processed to form fuel and/or chemical products. The methods can allow for removal of at least a portion of the oxygen in lignin, either during or after depolymerization of lignin to single ring aromatic compounds, while optionally reducing or minimizing aromatic saturation performed on the aromatic compounds. The methods can include use of quench solvent to control reactions within the product stream from a pyrolysis process and/or use of a solvent to assist with hydroprocessing of lignin, lignin-containing biomass, or a pyrolysis oil.

  • Patent number: 10071938
    Abstract: The invention relates to the production of aromatic hydrocarbon by the conversion of a feed comprising C2+ non-aromatic hydrocarbon, e.g., natural gas. The invention is particularly useful in converting natural gas to liquid-phase aromatic hydrocarbon, which can be more easily transported away from remote natural gas production facilities. The conversion is carried out in the presence of a dehydrocyclization catalyst comprising dehydrogenation and molecular sieve components. The dehydrocyclization catalyst has an average residence time of 90 seconds or less.
